subject: Xiao Bian Of China's Electronic Anti-theft Lock And Technology Trends - Electronic Anti-theft [print this page] Now common remote control Electronic Anti-theft lock the main two types of bright remote control and radio remote control. Remote control is divided into light and visible light remote control infrared remote control, light remote control using a narrow angle optical transmission password, the advantage of the amount of information can be transmitted great fast, the human eye can not spot, they can not light path (the operator and between subjects of electronic security locks) to capture the signal trying to copy machines, so the high degree of confidentiality. Radio remote control can be a great advantage is the amount of information transmission speed, the human eye can not spot, but the emission of the signal dispersion of space, easily capture device, so for a "change password", such as the so-called "jump code" "rolling code" (random changes are no obvious rules), so even if the signal was captured and no use, copy value. Use of remote control electronic anti-theft lock, carefully keeping the remote control (that is key), but for some applications, this key is a little, may need to use specific battery.
Electronic keyboard Lock
From the current level of technology and market acceptance of view, the most widely used is the keyboard, electronic lock, the product is mainly used in safe, safes and vaults, and also a safe and armored car used. Keyboard, electronic keyboard input code, and phone calls about, it is easy to grasp, its advantage is that the "Password" is recorded in the authorized number of human mind and character, both accurate and reliable and will not lose (except forget) difficult stolen (unless their disclosure). But the password can not be too simple, too simple to easily test the keyboard out to others, or may be bystanders moved to look out, resulting in lack of confidentiality. Of course, the password can not be too complicated, too complex to be confused himself, or the operation of the low success rate for a password, users are. Therefore, in order to carry forward the strengths and overcome weaknesses, keyboard electronic passwords are also constantly developing, such as "arbitrary code" technology allows the authorized person may, at its needs or preferences set the password, used often new; the "automatic changes password, "technology makes this the password will automatically change the password should be entered into the next, change the law is not known to others, so afraid of onlookers moved to look; inventiveness of the" keyboard-order display "technology makes the fixed keys on the keyboard bit characters per show is not fixed, and shows the narrow point of view can only be seen by the operator front, so even if the bystanders moved to look hard to see the action moves out of the password; "multiple code settings" technology allows a single set of codes is not necessarily effective for use over the separation of powers, need to enter a password more than two groups are accepted and approved, greatly improved confidentiality, enter the password if the order qualified or time period, then confidentiality can improve. Enter the password in the process, attempt to limit the test code, often enter the wrong code number or the number of hours entered incorrectly, that "blockade" keyboard, no longer accepts input operation. In short, despite the emerging new electronic anti-theft lock, but the keyboard, electronic anti-theft lock password is still "old is new again", not only in the market playing a leading role, and, often as other types of electronic anti-theft lock the auxiliary input means.
